Question

Sides of a triangle are in the ratio of 12 : 17 : 25 and its perimeter is 540cm. ​

Answer 1

Step-by-step explanation:

Let the sides of triangle=12x, 17x, 25x

Perimeter of triangle =12x+17x+25x=54x=540

;x=10

12x=120, 17x=170, 25x=250

Therefore Sides of triangle=120cm, 170cm, 250cm

Answer 2

Answer:

The sides of a triangle are in the ratio of 12 : 17 : 25 and its perimeter is 540cm. ​

12x + 17x + 25x = 540

⇒ 54x = 540

⇒ x = 540 ÷ 54

⇒ x = 10cm

12x = 12 × 10 = 120cm

17x = 17 × 10 = 170cm

25x = 25 × 10 = 250cm

∴ The sides of the triangle are 120cm, 170cm and 250cm.
